Two Achievements that Edberg never achieved....

I find this interesting, of the top 12 players of the open era (in no particular order): Federer, Borg, Sampras, Nadal, McEnroe, Agassi, Connors, Lendl, Wilander, Becker, Edberg, and Djokovic, only one player did not have at least one season of winning two grand slams in the same season.
